“Last night while at her home in L.A., Nichelle Nichols suffered from a mild stroke,” said Zach McGinnis of Galactic Productions, who represents Nichols. “She is currently undergoing testing to determine how severe the stroke was. Please keep her in your thoughts.”

Nichols was rushed to a Los Angeles hospital and is resting after undergoing treatment and tests, her representatives confirmed to TheWrap.

Nichols appeared in the original “Star Trek” TV series, which ran from 1966-1969, and reprised her role in six “Star Trek” films. She also played Nana Dawson in the TV series “Heroes” and voiced characters in the “Gargoyles” and “Spider-Man” TV shows.
